[0025] As Figures 1-4 shown, the present invention provides a technical solution: a construction scaffold, including four support rods 1 and a construction platform 2. A fixed block 4 is fixedly connected to the bottom of the construction platform 2. A groove 401 is opened in the fixed block 4. A spherical groove 402 is opened at the middle position of the groove 401. A spherical block 403 is rotatably connected to the inner peripheral wall of the spherical groove 402. The diameter of the spherical block 403 is greater than the inner diameters of both sides of the groove 401. A lead screw 404 is fixedly connected to the outer peripheral wall of the spherical block 403. A linkage block 405 is threadedly connected to the outer peripheral wall of the lead screw 404. Connecting shafts 406 are fixedly connected to both sides of the linkage block 405.

[0026] Specifically: a connection groove 101 is opened at the top of the support rod 1. Four guide rods 201 are symmetrically opened on both sides of the construction platform 2. The guide rods 201 are slidably connected to the support rod 1 through the connection groove 101. A chute 3 is opened in the support rod 1. A limit groove 301 is opened at the top of the chute 3. A limit shaft 302 is rotatably connected to the inner peripheral wall of the limit groove 301. A bracket 303 is fixedly connected to the outer peripheral wall of the limit shaft 302. The middle of the bracket 303 is rotatably connected to the linkage block 405 through the connecting shaft 406;

[0027] During use, first, the guide rod 201 is connected with the connecting groove 101 by clamping, so that the guide rod 201 can move based on the support rod 1, and vice versa, the support rod 1 can be deviated accordingly along the construction platform 2. At the same time, since the slide groove 3 is opened in the support rod 1, and the top of the slide groove 3 is opened with a limiting groove 301 to limit the limiting shaft 302, the limiting shaft 302 can then rotate in the limiting groove 301, but cannot be separated from the limiting groove 301, and after one end of the bracket 303 is connected to the limiting shaft 302, the bracket 303 can rotate with the limiting shaft 302 as the center, and the other end of the bracket 303 is located in the slide groove 3 in the other support rod 1, and When two crossed brackets 303 are connected, the two support rods 1 are connected thereby, and the middle position of the two brackets 303 serves as the intersection thereof, and is connected to the linkage block 405 through the connecting shaft 406 at this intersection, so that the two support rods 1 are always in a parallel state under this action, thereby ensuring the stability of the construction platform 2, and based on this, after the spherical block 403 in the fixing block 4 is fixed to the screw rod 404, the linkage block 405 is sleeved on the outer peripheral wall of the screw rod 404, and then, on the basis that the linkage block 405 itself cannot rotate, the operator can change the height of the linkage block 405 after manually rotating the screw rod 404, and then adjust the two The cross point of the bracket 303 is applied with a corresponding force so that the height of the cross position is also changed, that is, the cross angle between the bracket 303 and the support rod 1 is changed because the height of the limit shaft 302 at the end of the bracket 303 cannot be changed, so that the distance between the two support rods 1 can be changed due to the change of the bracket 303, so that the operator can indirectly change the distance between the two support rods 1 by rotating the screw rod 404, so as to control the floor space of the construction frame, so that the operator can adjust it according to needs, and at the same time, when the distance between the two support rods 1 is reduced to the minimum, the guide rod 201 will be disengaged from the connecting groove 101, so that the two sides of the construction platform 2 at this time The side is in an unsupported state, and a groove 401 and a spherical groove 402 are provided in the fixed block 4, and the diameter of the screw rod 404, the inner diameter of the groove 401, the diameter of the spherical block 403 and the inner diameter of the spherical groove 402 are arranged from small to large, so that the spherical block 403 cannot be separated from the spherical groove 402, and the screw rod 404 can be rotated with the spherical block 403 as the center. Therefore, the construction platform 2 can be flipped based on the structure in the fixed block 4, that is, the angle between the construction platform 2 and the support rod 1 can be switched from a perpendicular state to a parallel state, and then the construction frame can be folded, which is convenient for the subsequent operator to place or carry it, and the use effect of the construction frame is further improved.

[0028] The working process of the utility model is as follows: first, after the guide rod 201 is clamped with the connecting groove 101, the guide rod 201 can be moved based on the support rod 1, and vice versa, the support rod 1 can be deviated accordingly along the construction platform 2. At the same time, since the slide groove 3 is opened in the support rod 1, and the top of the slide groove 3 is opened with a limiting groove 301 to limit the limiting shaft 302, the limiting shaft 302 can then rotate in the limiting groove 301, but cannot be separated from the limiting groove 301, and after one end of the bracket 303 is connected to the limiting shaft 302, the bracket 303 can rotate with the limiting shaft 302 as the center, and the other end of the bracket 303 is located in the slide groove 3 in the other support rod 1. The two support rods 1 are connected by two crossed brackets 303, and the middle position of the two brackets 303 is used as the intersection. At this intersection, the two support rods 1 are connected to the linkage block 405 through the connecting shaft 406, so that the two support rods 1 are always in a parallel state under this action, thereby ensuring the stability of the construction platform 2. Based on this, after the spherical block 403 in the fixing block 4 is fixed to the screw rod 404, the linkage block 405 is sleeved on the outer peripheral wall of the screw rod 404, and then on the basis that the linkage block 405 itself cannot rotate, the operator can change the height of the linkage block 405 after manually rotating the screw rod 404, and then The intersection of the two brackets 303 applies a corresponding force so that the height of the intersection position also changes, that is, the end of the bracket 303 cannot change because the height of the limit shaft 302 cannot change, so the intersection angle between the bracket 303 and the support rod 1 changes, thereby the distance between the two support rods 1 can be changed due to the change of the bracket 303, so that the operator can indirectly change the distance between the two support rods 1 by rotating the screw rod 404, so as to control the floor space of the construction frame, so that the operator can adjust it according to needs, and at the same time, when the distance between the two support rods 1 is reduced to the minimum, the guide rod 201 will be disengaged from the connecting groove 101, and then the construction platform 2 at this time will be The two sides are in an unsupported state, and a groove 401 and a spherical groove 402 are provided in the fixed block 4, and the diameter of the screw rod 404, the inner diameter of the groove 401, the diameter of the spherical block 403 and the inner diameter of the spherical groove 402 are arranged from small to large, so that the spherical block 403 cannot be separated from the spherical groove 402, and the screw rod 404 can be rotated with the spherical block 403 as the center. Therefore, the construction platform 2 can be flipped based on the structure in the fixed block 4, that is, the angle between the construction platform 2 and the support rod 1 can be switched between a perpendicular and a parallel state, and then the construction frame can be folded, which is convenient for subsequent operators to place or carry it, and the use effect of the construction frame is further improved.
